Answer:
It'd take 0.93 years to obtain that value.
Step-by-step explanation:
Since we were given the initial amount and the interest rate, we wish to know the time to earn 900 from those values. So we can isolate the variable we wish to find, in this case it's the time t.
prt = x
t = x/pr
Now we can apply the values that were given to us:
t = 900/(0.046*21000) = 900/966 = 0.93
It'd take 0.93 years to obtain that value.
Answer:
55%
Step-by-step explanation:
Since the perimeter of the square is 40, its side length is 40/4 = 10, so its area is 100.
To find the percentage of the shaded area, I am going to find the unshaded areas, which consist of 2 triangles.
The one on the left has lengths of 10(side length of the square) and 3(10-7), which means it has an area of 10*3/2 = 15.
The one on the right has lengths of 10(side length of the square) and 6(10-4), which means it has an area of 10*6/2 = 30.
That means the unshaded area is 15+30 = 45.
To find the shaded area, just subtract 45(unshaded area) from 100(area of square), which is 55 cm^2.
55 cm^2 is exactly 55% of 100, so the answer is 55%.
I hope this helped you.
